IMPROVEMENT IN OIL-BURNERS.

Specification forming part of Letters Patent No. 183,814, dated October31, 1876; application led March 22, 1876.

To all whom it may concern Be it known that I, GEORGE K. OsBoEN, ofBrooklyn, in the county of Kings and State of New York, have'invented anew and useful Improvement in Oil-Burners, which improvement is fullyset forth in the following speciication, reference being had to theaccompanying drawings.

The object of my invention is to construct an Argand oil-burner in whichmay be used a permanent fixed wick, which will give a steady light andemit little or no odor.

Figure l is an outside view of my burner. Fig. 2 is a sectional View ofFig. 1. Fig. 3 shows the slide d d removed from the rest of the burner.Fig. 4 shows the dripcup o removed from the burner. Fig. 5 is avertical- View of Fig. 1 bisected on the line a' fr.

T is the handle, by means of which the slide d d is moved. a a, is theouter cylinder of the burner. b bis the inner cylinder. F F is apermanent fixed wick, and is merely a cylinder filling the space betweenthe cylinders a a and b b. d d is a sliding tube fitting snugly inside bb, and is raised and lowered by means of its handle T, therebyregulating the amount of flame.

The advantage gained by having the permanent wick exposed on the inside,instead of the outer or both sides, as is usually the case, is that itsecures a steady light, the current of air on the inside being moreuniform than on the outside, and less affected by drafts of air. With acommon cotton wick the advantage is :not so marked, as theburning-surface is not so great.

c c is a drip-cup placed inside the inner tube b b, and near the top, sothat the slide d d e11- ters it, conveying sufficient heat to the oilthat collects in it to vaporize it. The vapor is discharged into theflame and is consumed, thereby avoiding the odor arising from drip-cupswhen placed at the bottom of the burner. e is the inlet to the burnerfor oil.

When a common cotton wick is used with the inside slide-tube, the oiloverflows the tube rapidly, and would be useless for any illuminatingliquid other than those which vaporize easily, as naphtha,burning-fluid, Sto.; but with a permanent wick, which must stand agreater degree of heat, owing to the larger burningsurface, the insideslide has marked advantages over exposing the wick on the outside, or onboth sides.

I claim and desire to secure by Letters Patent- 1. The slide d, placedwithin an Argand burner, and worked as and for the purposes set forth.

2. The combination of the drip-cup c with the sliding tube d, arrangedas and for the purposes set forth.

3. A combination of the slide d and the permanent fixed wick F,operating as and for the purposes set forth.
